SPECIFICATION forming part of Letters Patent No. 380,317, dated April 3, 1888.

Application filed April 5, 1887. Serial No. 233,809. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES LOUIS FLEIsoH- MANN, a citizen of the United States, residing in Washington, in the District of Columbia, have invented a new and useful Improvement in Sewing-Machines, of which the following specification is a full, clear, and exact description.

Myin-vention relates to mechanism for moving the needle-bar and shuttle.

The invention, stated in very general terms, consists, first, in a reciprocating shuttle-carrier combined with a star-wheel or many-armed lever and connections with the needle-bar, whereby the needle is properly reciprocated to carry the thread through the cloth, make the loop to receive the shuttle-thread, and then tighten said loop to finish the stitch.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1 is a perspective view of the machine applied to one corner of a table. Fig. 2 is a rear end elevation of the machine on a larger scale. Fig. 3 is a plan view. Fig. 4. is a side view of the shuttle-carrier in its rearmost position, and Fig. 5 is a similar view in its foremost position.

The head of the machine, the presser-foot, the shuttle, and the feed may be of any approved construction. The bed-plateA is provided with a suitable number of legs, a a, and may be provided with a clamping device, A, for securing the machine to the table.

B is the neck, having the head B,which receives the presserfoot bar B and needle-bar B. The bed-plate A is provided with the rearwardly-extending arms A which form journals for the shaft D D, the cranked end of the shaft being designated D. On this shaft is arranged a band wheel or pulley, O.

Suitably supported in the bed A is a slide, 1:, herein referred to as the shuttle-carrier, the shuttle being arranged in any suitable manner in the forward end of the said slide. This slide is given a reciprocating motion by means of a link, E, connecting it to the crank D, which crank, as will appear presently, has a rotary motion imparted to it. The shuttle-carrier F is provided with a series of pins or studs, G H I, projecting laterally from one face thereof, and these pins are engaged, in the manner hereinafter more particularly set forth, by the starwheel or many-armed lever N, pivoted to the arm B, this lever being in turn connected by a slotted link or rod, 0, with the lever M, the last-named lever, M, being pivoted to the arm B and loosely jointed to the needle-bar B As the driving mechanism I may employ a treadle, R, arranged upon a treadle-stand, R, which may be suitably secured to the floor, the said treadle-stand having projecting from and hinged to it a frame, R", in which is j ournaled a wheel, U. This wheel U is connected by a pitman, B with the treadle R in any ordinary manner of driving a wheel by means of the pitman and treadle. A band, S, extends from the wheel U to the wheel 0. Hooks T, hinged to the frame R are adapted to be engaged with lugs O G, projecting laterally from the arms A A-,whereby the said driving-frame is supported from the machine-bed. By hinging together the parts of the driving mechanism it may be folded together very compactly for transportation and storage.

The operation is as follows: Rotary motion being given to wheel U by means of the treadle R and the connecting-pitinan R thebelt transmits said motion to the pulley G, and it in turn rotates the crankshaft D D. This motion of the crank-shaft imparts a reciprocating motion in a right line to the shuttle-carrier F, through the medium of the link E. When the shuttle-carrier is drawn in the direction of the wheel 0, the shuttle is placed somewhat beyond the needle, so that the point of the shuttle comes close to the needle-loop, while the stud or pin H pushes back the arm 6 of the wheel or lever N. This motion raises the arm 0 of said wheel or lever N, and of course it presses down the curved arm d of said lever or wheel. By this motion the connecting-rod O, which is jointed to the arm a, is raised and forces down the needle-bar through the lever M, so as to cause the needle to penetrate the goods. By this time the shuttle-carrier has finished its backward movement, and now begins its return-stroke. On this return-stroke the shuttle-carrier has alost motion of about two inches before the stud I comes in contact with the arm I), so that the stud G has time to move out from under the arm (1, thereby drawing down the rod 0 and theleverM, and partly elevating the needlerod to form the thread- 100p. As soon as the stud G is free from the arm 6, the shuttle enters the loop and at that moment the stud I engages the arm b and causes the lever M to draw the needle from the goods and finish the stitch, and at this time 5 the shuttle-carrier is again withdrawn, ready to go through the same motions again. The slot 1?, in the connection of the link 0 with the lever M, gives the necessary slack motion to permit the formation of the thread-loop.

IO What I claim is- 1. In a sewing-machine, a reciprocating needle-bar and needle, and a reciprocating shuttle, combined with a shuttle-carrier pro vided with studs or pins G H I, and a many- 15 armed lever engaged by said studs or pins, and
